Beginning the infiltration was simple. All Damien had to do was walk into the dome-like structure as if he belonged there in the first place. Nobody questioned him and nobody stopped him, there wasn't even any sort of identification point inside.
Damien walked in a pompous manner as if he viewed himself as someone above everyone surrounding him, and this air alone made people avoid him. Nobody liked conversing with pretentious people.
The area of the dome-like structure was mostly empty, with some training rooms that seemed to be there solely as cover for everything happening underneath. Scattered around the area were plenty of elevators, one of which Damien took.
The numbers on the elevator were a quick indicator of how status worked. From 4 through 64, anyone could travel, but to go below floor 65, there was some sort of keycard identification necessary.
